Re: Gigabit speed test anybody?
Ironically, two days later, I find myself in exactly the same position; needing an iperf box to test a 100Mb client connection against. In a perfect world, this box would hang off of NYIIX (or Arbinet) and be able to sustain 100Mb of throughput for the duration of a couple of generic iperf tests that I need to perform at a client site in a couple of hours. Thanks in advance... On 26-Mar-09, at 11:57 AM, Rick Ernst wrote: Thanks to multiple private/public responses. I was able to get an iperf test and also a close mirror for a DVD iso.

RE: Gigabit speed test anybody?
I believe there is an ITU standard for testing that could be looked at, but if you went with the same test gear that SPs use to test their circuits, I think you would be safe. Hence my mention of JDSU, but I could also add Agilent (more engineering focused), Anritsu, EXFO, Fluke (more enterprise focused), and SR Telecom.

From: char...@thewybles.com Date: Fri, 27 Mar 2009 22:47:17 + Owamp? owamp is a latency measurement tool. While we find it invaluable, I'm not sure how it fits in here. We use iperf on high-performance systems with a lot of tuning and Myricom 10GE cards to test 10 Gig circuits (10GE or OC-192). No particular endorsement of Myricom. We also qualified Chelsio. At the time we tested, TSO on the Chelsios caused some problems when the other end was a Myricom, but TSO is easily turned off. -- R.

RE: Gigabit speed test anybody?
Rick. The speedtests are only as good as the hosts they're hosted on and the path by which you reach them. I use iperf on each end of a link that I'm turning up. I put Linux hosts at both endpoints, but I believe iperf comes in a windows flavor too. -b From: Rick Ernst [er...@easystreet.com] Sent: Wednesday, March 25, 2009 11:05 AM To: nanog@nanog.org Subject: Gigabit speed test anybody?

RE: Gigabit speed test anybody?
Yup. I use iperf for point-to-point testing, but this is an access connection which is why I'm looking more for some kind of test host on Level3 in Seattle rather than a speed test site per se.

RE: Gigabit speed test anybody?
Hi Rick, Try an anon ftp or http download from http://ftp.heanet.ie The cluster that serves for ftp.heanet.ie has multiple machines with at least single or bonded 10GE interfaces into HEAnet's backbone and then minimum of 10GE on two carriers to the general internet. Should give you a pretty good speed test. I can max out our GigE links using them for testing.

You might want to calculate what maximum throughput you can get on one TCP session (c.f. windowsize and bandwidth delay product when taking into consideration the RTT between the two endpoints of your test), then start multiple of these sessions in parallel to fill up your pipe. I strongly urge you to use a test like netperf/iperf that runs completely from memory and does not require spinning disks like http/ftp servers usually do. -andreas -- Andreas Ott K6OTT andr...@naund.org
Re: Gigabit speed test anybody?
I turned-up a pair of 10GigE circuits a while back (with a different, unnamed carrier). They didn't perform too well. When I pushed them for assistance with testing, they revealed that they had multiple IPERF transponders scattered throughout their network. They were not open to the public, but could be made available for short periods of time (timer-based, requiring repeated re-authorization to use them for an extended period). It seems likely that Level3 has similar (or superior) testing facilities. A call to some account executives may be required to open the kimono. Separately, the Super computer centers used to have speed-test servers installed adjacent to their border routers. They were dedicated, tuned hosts specifically for speed testing. One/more of them might be willing to help you out. However, unless one of them happens to use Level3 for commercial transit, your performance will be gated by the excess intervening network(s) and under all circumstances, by the competing traffic on their access circuit. Finally, I echo the sentiments about avoiding disk I/O. If you do use FTP download for testing, you may wish to write the local output to the null device. Some ftp clients allow the null device to be specified as the local output file when downloading files. On XP command-line FTP, the device Nul: is accepted. On Un*x it is /dev/null. The command-line client on Server 2003 et al does not seem to accept Nul as the local destination file when downloading. (anyone know the correct magic?)Remember to download multiple times; assuming the source server has enough ram, it will cache the file in memory during the first download and successive downloads in rapid succession should be essentially memory-to-memory (if you're using a null device on the receiving end) Bob Rick Ernst wrote: Resent from my subscribed address.

If you're turning up a 10 GigE circuit, as a customer I would be asking for that circuit to be tested with some modern tools such as the JDSU T-BERD.

Re: Gigabit speed test anybody?
The attachment circuits physical media was single mode dark fiber mid-span meet. After some tinkering with colo center jumpers, the physical attachment circuits were rock solid. The issue was the internal IP network of the ISP (or lack of same). You get what you pay for. (At most. Quite often, you get less.)
